Can anyone help with this? I have xp. I don't know how I managed to do this, but i have blocked access to anything. It says "Windows doesn't have access to control panel, or windows media player, or desktop settings. "You may not have access rights". For everything basically. Every program except superantispyware. It doesn't allow me to enter even Zone Alarm, first I thought I did there something. I tried the safe mode but I'm blocked there too.I tried administrator mode, but I'm blocked there as well. ...thanks
